2560 × 1600 scaling missing in Big Sur for the built-in display
I recently updated to Mac OS Big Sur and I noticed that everything is bigger on my screen and if I remember, there were 5 display scaling options in settings, but now there are only 4 and it is missing the one I was using which is 2560 x 1600. I've looked online but couldn't find any answer regarding the built-in display scaling.
I have tried using the alt/option key and click on "scaling" but it doesn't seem to work with the built-in display. I've reset the NVRAM/PRAM and it didn't change anything.
My setup: Macbook Pro 2014 retina 13 inches. There is NO external monitor attached to it.
